FEEDING DEVICE FOR USE WITH ENDLESS CONVEYERS AND THE LIKE Filed Feb. 20, 1940 Patented Mar. 17, 1942 FEEDING DEVICE FOR USE WITH ENDLESS CONVEYERS AND THE LIKE Matthew Smith Moore, Malvern, England, as-

sig'nor of one-half to The Mining Engineering Company Limited, Worcester, England Application February 20, 1940, Serial No. 319,980 In Great Britain February 24, 1939 3 Claims.

This invention relates to feeding devices for endless conveyers and the like of the type comprising a rotary loader member such as a toothed bar extending parallel to the conveyer or across the end of the conveyer and a comb-shaped piece arranged in the gap between said bar and conveyer, and adapted to receive the material raised by the bar teeth or picks as disclosed in my prior Patent No. 2,031,544. Such combs are preferably provided with removable teeth or picks made of hard, wear-resisting material, which are fitted in slots in the outer edge of the comb body. This edge is nevertheless exposed to heavy wear, being subjected to severe friction and pounding by the material handled by the bar. It is liable to be quickly damaged, the replacement of the entire comb, or at least of the damaged comb section, then being necessary. 7

This drawback is avoided in carrying out the present invention by providing the removable comb picks or teeth with laterally projecting shoulders. Preferably adjacent shoulders on adjoining picks in the comb are adapted mutually to engage each other and to form together a continuous reinforced edge in front of the comb.

Referring to the accompanying drawing:

Figure 1 shows one embodiment of a comb pick, according to the invention, in side elevation,

Figure 2 being a front elevation, and

Figure 3 a plan view of same,

Figure 4 is a plan view illustrating a comb section with comb picks as shown in Figure 1,

Figure 5 is a plan view of a second embodiment of comb pick, according to the invention, and

Figure 6 a plan view illustrating a comb section with comb picks as shown in Figure 5.

In the drawing I is the comb pick which is fitted with the usual tail piece or stem 2 adapted to be inserted in a hole 3 in the comb body 4. According to the embodiment illustrated in Figures 1 to 4, the pick I has two reinforcing lateral shoulder portions 5 which fit against the comb body. As will be seen from Figure 4, the shoulders 5 on adjacent picks, mutually engage each other so that they then form together a continuous reinforcing bar or rib which will receive the impact of the lump material being treated and thus protect the comb body from wear and breakage.

The shoulders 5 are recessed at 6 to allow of the bar teeth or picks passing thereunder, and preferably the ends of the picks are rounded as shown at 1.

If desired only one lateral shoulder 5 need be formed on each pick I as shown in Figure 5, the said shoulders being arranged on the same sides of the picks so that when assembled as shown in Figure 6 they also form a continuous reinforcing bar or rib.

I claim:

1. In feeding devices for conveyors of the type referred to wherein a rotary toothed loader bar cooperates with a comb device, the combination of a comb body, a plurality of comb picks held by the outer edge of the comb body, shoulders on the comb picks which laterally project and fit against the comb body and also space the picks apart and form a protection for the outer edge of the comb body.

2. In a feeding device for conveyers of the type referred to wherein a rotary toothed loader bar cooperates with a comb device, the combination of a comb body, comb picks held on the outer edge of the comb body, shoulders on the comb picks which mutually engage those of the adjoining picks so as to form together a continuous reinforced edge in front of the comb body.

3. In a feeding device for conveyers of the type hereinbefore referred to, the combination of a comb body, comb picks held on the outer edge of the comb body, shoulders on the comb picks which mutually engage those of the adjoining picks so as to form together a continuous reinforced edge in-front of the comb body and in which theunder surface of the laterally projecting shoulders are recessed to allow loader bar picks passing therebeneath.
